Scaffolding Grows Replacement Human Trachea

Maria Konovalenko points to an impressive feat of tissue engineering. Using the cartilage of a donor trachea to form a scaffolding the stem cells from the nose and bone marrow of a 19 year old girl were grown on the cartilage scaffolding and then the new windpipe was implanted as a replacement for a cancerous trachea.

A British teenager has been given a new windpipe grown from her own stem cells in a pioneering operation. The 19-year-old has now been discharged after having the procedure in Italy.

Curiously, this is not the first success at growing replacement tracheas. Whether the stem cells are first grown on the trachea for a while before implantation has differed in the few times trachea replacements have been installed. Click thru to read the details.

The use of donor organ non-cell scaffolding to grow replacement organs has also been done with rat livers. MIT researchers have created scaffolding for growing knee and other joint tissue. Other research shows promise for creating scaffolding to grow heart tissue replacements.

Nice article for the task of the scaffolding. I think you are right for this matter.
